Abstract
The utility model relates to a liquid medicine circulation device for etching cabins of a high-density interconnection circuit board DES (developing, etching and stripping) line body. Each etching cabin and a valve matched with the etching cabin are respectively connected with the two ends of a three-way pipe, third ends of the three-way pipes are connected with a conveying pipe, the conveying pipe is connected with a liquid storage tank in a vertical position which is lower than the etching cabin through a liquid inlet valve, the outlet of the liquid storage tank is connected with the inlet of a filter through a liquid discharge valve and a pump, and the outlet of the filter is connected with the inlet of the liquid inlet valve. In the liquid medicine circulation device provided by the utility model, a tee is mounted at the outlet of each existing etching cabin, and then all the tees are connected to the liquid storage tank in the lower vertical position; by combining the opening and closing states of the different valves, a liquid medicine can automatically enter the liquid storage tank and then wash the etching cabins, a waste liquid is still discharged into an acidic waste liquid discharge pipe, after cleaning is finished, a pump is utilized for enabling the liquid medicine to return into the etching cabins after the liquid medicine passes through the filter, the efficiency of the whole process is high, manpower is saved, and the liquid medicine can be fast evacuated during emergency shutdown repair.
Description
Technical field
The utility model belongs to etching line body maintenance technical field, especially a kind of high-density interconnected circuit board DES line body etching storehouse liquid circulation device.
Background technology
The outer figure of high density interconnect board production changes a job in order and is provided with DES line body, this line body comprises development, etching and stripping, and development is that the place on line dry film that will retain remains, and etching forms circuit, stripping divests dry film, and visible DES line body is determining the final quality of product.Many DES line bodies generally are set when producing, situation such as two common line bodies settings, the volume in the etching storehouse in two line bodies is respectively 1.6 cubic metres and 2.3 cubic metres, by processing requirement, these two etching storehouses should all be cleaned in each season, and liquid is through filtering, and cleaning cell body liquid need to be used the bucket of 20 200 liters to collect, workload is very large, has greatly wasted artificial.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, maintenance rational in infrastructure, quick is provided, saves artificial a kind of high-density interconnected circuit board DES line body etching storehouse liquid circulation device.
The technical scheme that the utility model is taked is:
A kind of high-density interconnected circuit board DES line body etching storehouse liquid circulation device, comprise at least one etching storehouse, this etching storehouse all connects an acid waste liquid delivery pipe by valve, it is characterized in that: the valve matched with it in each etching storehouse is connected respectively the two ends of a Y-tube, the 3rd end of this Y-tube connects a transfer lime, this transfer lime connects a vertical position than the low container for storing liquid in described etching storehouse by a liquid feed valve, the outlet of this container for storing liquid connects the import of a strainer by tapping valve, pump, the outlet of this strainer connects the import of described liquid feed valve.
And, the outlet of the described strainer control valve of connecting.
Advantage of the present utility model and positively effect are:
In the utility model; in existing each etching storehouse outlet, threeway is installed, then all threeways is connected to the container for storing liquid that vertical position is lower, by the combination of different valve folding conditions; realized that liquid enters container for storing liquid automatically; then rinse the etching storehouse, waste liquid still enters in acid non-also delivery pipe, after cleaning out; after utilizing pump to make liquid by strainer, return in the etching storehouse; whole process efficiency is high, saved manually, and can be fast that liquid is emptying when emergent shutdown is repaired.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with embodiment, the utility model is further illustrated, following embodiment is illustrative, is not determinate, can not limit protection domain of the present utility model with following embodiment.
A kind of high-density interconnected circuit board DES line body etching storehouse liquid circulation device, as shown in Figures 1 to 3, comprise at least one etching storehouse 1, this etching storehouse all connects an acid waste liquid delivery pipe 13 by valve 6, innovation of the present utility model is: the valve matched with it in each etching storehouse is connected respectively the two ends of a Y-tube 3, the 3rd end of this Y-tube is all by one minute valve 2, 4 connect a transfer lime 5, this transfer lime connects the vertical position container for storing liquid 9 lower than described etching storehouse by a liquid feed valve 8, the outlet of this container for storing liquid is by tapping valve 10, pump 11 connects the import of a strainer 12, the outlet of this strainer connects the import of described liquid feed valve.
In the present embodiment, the etching storehouse is two, and these two etching positions in storehouse are in the production site of Stall, and container for storing liquid is positioned at vault, and liquid can be flowed freely in container for storing liquid.The outlet of the strainer control valve 7 of connecting.
When the utility model is used:
1. two valves 6 are closed, open minute valve 2,4 and liquid feed valve 8, close tapping valve, now the liquid in the etching storehouse flows in container for storing liquid through transfer lime;
2. after the liquid streamer, close minute valve 2,4, open valve 6, make the waste liquid of clearing up the etching storehouse enter the acid waste liquid delivery pipe;
3. after having cleared up, valve-off 6, open minute valve 2,4, open tapping valve 10 and control valve 7, close liquid feed valve 8, ejector priming flow back in two etching storehouses liquid after filter is processed.
In the utility model; in existing each etching storehouse outlet, threeway is installed, then all threeways is connected to the container for storing liquid that vertical position is lower, by the combination of different valve folding conditions; realized that liquid enters container for storing liquid automatically; then rinse the etching storehouse, waste liquid still enters in acid non-also delivery pipe, after cleaning out; after utilizing pump to make liquid by strainer, return in the etching storehouse; whole process efficiency is high, saved manually, and can be fast that liquid is emptying when emergent shutdown is repaired.
Claims (2)
